Nouns denoting natural phenomena
- alternation of generations
- the alternation of two or more different forms in the life cycle of a plant or animal
- diffraction
- when light passes sharp edges or goes through narrow slits the rays are deflected and produce fringes of light and dark bands

- raindrop
- a drop of rain
- by-product
